Deer Creek Fire
The Deer Creek Fire was a fast-moving, destructive wildfire that burned north of La Sal, Utah, United States. The human-caused wildfire ignited on July 10, 2025, and quickly grew to over that night. On July 12, the blaze generated a rare fire whirl, which damaged one fire engine. The fire crossed over into Montrose County, Colorado, on July 15. Higher humidity and weakened winds slowed fire growth and aided fire suppression efforts later in July, and evacuations were lifted in Montrose County on August 8. The Deer Creek Fire reached 100% containment on August 11, after burning and destroying 13 structures.
Background
Strong winds influenced the formation of a fire tornado over the Deer Creek Fire. Strong wind gusts coming off the La Sal Mountains, flowing over the mountains like a river over rocks. The mountains disrupted the wind, creating a body of swirling air, spinning flames into the mostly stationary fire tornado. Rugged terrain and limited road access complicated fire suppression efforts.Cause
The Deer Creek Fire was first reported around 3 pm on July 10, 2025 near State Route 46. After an investigation, the San Juan County Sherriff released in a statement on July 21 the fire was human-caused, and a suspect was identified. Charges were filed against 68-year-old Scott Carrier of Salt Lake City in connection with the fire's ignition. Carrier stated he burned piles of sagebrush in winter, but did not burn around the time of the fire. The probable cause of the Deer Creek Fire was a pile of debris burning or discarded ashes from a warming or cooking fire, with two origin spots detected.Progression
July
The Deer Creek Fire was reported around 3 pm on July 10, estimated at. State Route 46 was closed, and those within of the fire were asked to evacuate. The blaze spread to an estimated by that evening. Winds were gusting up to, with humidity as low as 6%. The fire rapidly spread, reaching by the next morning. Several structures had been impacted, and the fire was driven by hot, dry, windy conditions. Crews prioritized in structure protection near the south and west edges of the perimeter. That afternoon, size increased to, still at 0% containment. Four homes, five outbuildings, and power infrastructure had been destroyed. Twenty homes remained threatened, and 250 residents were evacuated.On July 12, the fire formed a rare fire-induced tornado. The fire whirl damaged outbuildings and residential structures, and one fire engine that was released for repairs. The tornado remained on the ground for twelve minutes and remained mostly stationary. While most structures damaged by the fire whirl were destroyed by separate flames later, wind damage on remaining ones led to the fire to be rated EF2 on the Enhanced Fujita scale. Several more crews arrived at the fire that day, and size increased to. Winds were spreading the fire into heavily forested areas.
While terrain-driven winds drove the fire closer to the Utah/Colorado border, making the fire on July 13, flames moved into the Hangdog Creek Fire burn scar of 2002, and fire intensity reduced. The fire's southern edge remained less active and had not spread, holding on State Route 46. The fire jumped to, still at 0% containment despite over 300 personnel on the fire. Firing operations were completed, removing vegetation in the fire's path. Air quality levels in Moab reached unhealthy levels due to the fire's smoke. Despite this, fire lines around the perimeter were strengthened from slackening winds and more suppression resources arriving, mostly along the southwestern edge.
While the Deer Creek Fire grew to roughly and crossed the Colorado state line, 7% containment was achieved. While over 400 personnel were assigned to the fire, containment remained at 7% and size increased to on July 16. An evacuation order in San Juan County was lifted, and a checkpoint would be at the entry road. Size jumped to the next day. The fire was burning through live, dead, and downed aspen, and the dry fuel in the dead and downed trees fueled the fire. A Temporary Emergency Closure was affecting roads near Paradox, Colorado.
Containment increased to 11% July 18 from cooler conditions, cloud cover, and lighter winds, despite the fire expanding to. While some evacuations were lifted in Utah, pre-evacuations were issued for residents in Colorado. Isolated rain on the southeast part of the fire, which contributed to containment raising to 17%. More evacuees were permitted to return home. Firing operations occurred along the northern edge in Colorado, as progress was made in the southeast area with containment to 22%. Still, the fire grew to.
While the Deer Creek Fire grew slightly to, weakened winds, lower temperatures, higher humidity, and cloud cover helped crews increase containment to 54% by the morning of July 22. These weather conditions allowed some crews to move from suppression to restoring the landscape on the western edge. That evening, size and containment increased to and 77%, respectively, again due to decreasing temperatures. By the next day, size increased to.
August
Firefighters made progress on the fire, and containment jumped to 93% by August 3. As containment increased to 97% five days later, all evacuation levels in Montrose County were lifted. However, some evacuations remained in Utah near Old La Sal.100% containment was achieved on the Deer Creek Fire on August 11, and remaining evacuations were lifted in San Juan County. Crews would remain on scene to monitor the fire.
Effects
A total of thirteen structures were destroyed by the Deer Creek Fire, including eleven residential structures, a United States Department of Agriculture structure, and a communications site. Several structures received wind damage from the fire tornado, rating it EF2 on the Enhanced Fujita Scale.The River Canyon Wireless transmission tower was destroyed, which was an Internet source for residents who relied on Wi-Fi to call. Residents had to temporarily move from Old La Sal to La Sal, Utah for another transmission tower or rely on fiber-optic communication or satellite Internet. Power was restored on July 23.
Suppression efforts cost slightly over $24 million. Costs on ranching are expected to cost at least $1 million, in terms of hay, fencing and structures destroyed, and destruction of pasture lands.
Residents were ordered to evacuate in Old La Sal, parts of Montrose County, Colorado, and anyone within five miles of the blaze. Utah State Route 46 was closed during the fire. A forest closure affected parts of the Moab Ranger District in Manti-La Sal National Forest until August 15.
Heavy equipment operators began repairing environmental damage to forest roads and access points by July 24, and overall, officials stated rehabilitation work once finished will have lasted weeks or months.
